Get free apps from Amazon Appstore for non-US users

I won't get into the details. Generally other then an Amazon account, you need two key items:

1. Access to a US VPN.
2. Amazon One-click set to a US postal address.

You can only purchase through the PC browser then download the apps through the Amazon Appstore app. I have not tried VPN on a mobile device but it may work.

That's really all there is to get free apps from Amazon Appstore. This should also work for Kindle and MP3 store. 

Warning: Try not to use your main Amazon account if the US address is not yours.
